Docker downloads all updates into a directory in /Users/$USER/Library/Caches/com.docker.docker/org.sparkle-project.Sparkle Let's make this directory inaccessible to the user under which Docker is going to run (you).

Switch to root user:

  sudo su

Change directory ownership and prevent access to other users:

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

My preferred code style is 2-space K&R. This is intended to provide a justification for this style.

Why K&R?

K&R style has the following properties:

Provides symmetric size (in terms of screen space consumed) between the opening and closing syntax of a clode block.
Forces no empty or meaningless lines, thereby avoiding artificial distance between related things that should be together.
Consumes the minimum vertical space while keeping the opening and closing syntax of a block on separate lines from the content.
